Sonboli, A. and Oberprieler, Christoph (2010) Phylogenetic relationships and taxonomic position of Xylanthemum tianschanicum (Krasch.) Muradyan (Compositae, Anthemideae) as inferred from nrDNA ITS data. Biochemical Systematics and Ecology 38, pp. 702-707.

The central Asian endemic Xylanthemum tianschanicum (Krasch.) Muradyan (Compositae, Anthemideae) is the only species of Xylanthemum Tzvelev with radiate capitula. While the species was formerly found to be closely related to members of the subtribe Handeliinae, other representatives of the genus were considered to be similar to members of Tanacetum. In order to assess its phylogenetic relationships and taxonomic classiﬁcation, a molecular analysis based on ITS sequences of 13 representatives of the subtribe Handeliinae and 17 species of three other subtribes (Anthemidinae, Artemisiinae and Matricariinae) was performed. Due to the close relationship of the X. tianschanicum to the type species of Richteria (Richteria pyrethroides) in a well supported clade (PP ¼ 1, BS ¼ 100%), which is supported bymorphological features concerning the indumentum, capitulum morphology, and pappus structure, the combination Richteria tianschanica (Krasch.) Sonboli & Oberpr. is proposed based on the basionym Pyrethrum tianschanicum Krasch.
